It is the object of this work to show that, in our eagerness to make the ocean liner fast and luxurious, we have forgotten to make her safe.

The safest ocean liner was the Great Eastern; and she was built over fifty years ago. Her designer aimed to make the ship practically unsinkable—and he succeeded; for she passed through a more severe ordeal than the Titanic, survived it, and came into port under her own steam.

Since her day, the shipbuilder has eliminated all but one of the safety devices which made the Great Eastern a ship so difficult to sink. Nobody, not even the shipbuilders themselves, seemed to realise what was being done, until, suddenly, the world's finest vessel, in all the pride of her maiden voyage, struck an iceberg and went to the bottom in something over two and a half hours' time!

If we learn the lesson of this tragedy, we shall lose no time in getting back to first principles. We shall reintroduce in all future passenger ships those simple and effective elements of safety—the double skin, the longitudinal bulkhead, and the watertight deck—which were conspicuous in the Great Eastern, and which alone can render such a ship as the Titanic unsinkable.
